I understand your concern. I too have worried about "pressuring" the goose to lay a larger clutch by taking the eggs. I keep imagining her going to the nest thinking "I must be losing my mind - I could have sworn I've laid a ton here already".
If you want to emulate a more natural laying situation, you can leave fake eggs for her in the nest. Golf balls make fine egg substitutes, or you can blow out some of her own eggs and fill them with caulk or plaster. They'll be heavier than real eggs, but my geese have accepted them.
Just make sure the filling has set before placing them in the nest. I was impatient with a couple of caulk-filled eggs once because this type took many days to set. A magpie broke one in the nest (gooey caulk everywhere) and flew off with another (poor magpie with a sticky beak).
